Astringent post is a very unpretentious tinder fungus. It is found everywhere, drawing attention to the white color of the fruit bodies.

Also, this mushroom has a very interesting feature – young bodies often gutt, emitting drops of a special liquid (as if the mushroom is 'crying').

Postia astringent (Postia stiptica) is an annual tinder fungus, has medium-sized fruit bodies (although some specimens can be quite large).

The shape of the bodies is different: kidney-shaped, semicircular, triangular, shell-shaped.

Color – milky white, cream, bright. The edges of the caps are sharp, less often blunt. Mushrooms can grow singly, as well as in groups, growing together.

The pulp is very juicy and fleshy. It tastes very bitter. The thickness of the caps can reach 3-4 centimeters, depending on the growing conditions of the mushroom. The surface of the bodies is naked, and also with slight pubescence. In mature mushrooms, tubercles, wrinkles, and roughness appear on the cap. The hymenophore is tubular (like most tinder fungi), the color is white, maybe with a slight yellowish tinge.

Season and habitat of the fungus

Postia astringent (Postia stiptica) is a mushroom that is unpretentious to the conditions of its habitat. Most often, it grows on coniferous wood. Rarely, but still you can find posttia knitting on deciduous trees. Active fruiting of mushrooms of this genus occurs from mid-summer to the very end of autumn. It is very simple to identify this type of mushroom, because the fruiting bodies of the postia astringent are very large and taste bitter.

Posttia viscous bears fruit from July to October inclusive, on stumps and dead trunks of coniferous trees, in particular, pines, spruces, fir. Sometimes this type of fungus can be seen on the wood of deciduous trees (oak, beech).

Edibility

Astringent postia (Postia stiptica) is one of the little-studied mushrooms, and many experienced mushroom pickers consider it inedible because of the viscous and bitter taste of the pulp.

Similar types and differences from them

The main species, similar to the astringent post, is the inedible poisonous mushroom aurantioporus fractured. The latter, however, has a milder taste, and grows mainly on deciduous wood. Mostly fractured aurantioporus can be seen on the trunks of aspens or apple trees. The outwardly described type of mushroom is similar to other fruiting bodies from the genus Tyromytes or Postia. But other varieties of mushrooms do not taste as viscous and rancid as Postia stiptica.

Other information about the mushroom

Droplets of transparent moisture, sometimes whitish in color, often appear on the fruiting bodies of the post astringent. This process is called gutting, and it manifests itself mainly in young fruiting bodies.
